Marken Projects is working on another Passive House in British Columbia. This 3,500-square-foot home, made with a panelized prefab system like the Rainbow Duplex, will house two families and three generations under the same roof in Surrey, British Columbia. The aim is an affordable structure that uses 90% less energy for heating and cooling than a standard home. It’ll have triple-pane windows, an HRV, solar hot water, rainwater harvesting, no-VOC materials, and the ultra-efficient and airtight shell. Construction will take about five months, and I’ll provide an update with more detail at that time.

The main driver for the performance and affordability of the recently-mentioned Rainbow Duplex is a panelized prefab system of construction that was designed to help projects meet the Passive House standard. BC Passive House in Canada has a manufacturing plant that’s making these panels, and I thought it would be interesting to share what’s inside the company’s next-gen, high-performance panels.

This is a follow-up with new photos to our original coverage of an affordable Passive House duplex located near an affluent ski resort in British Columbia. Referred to as the Rainbow Duplex, the home was designed by Marken Projects and built by Durfield Constructors with a high-performance, panelized prefab system by BC Passive House.
